 Our
Series 70 Manual Pinch Valve is the counterpart
to the unique Series 75 and has the same design
features and advantages, but the heavy cast iron
housing is eliminated and a strong fabricated
steel body is in its place. The Series 70
is less costly, lighter, versatile, and can be
used when the location of the valve is not exposed
to attack from corrosives or other volatile material.
The
Series 70 is available in the same sizes and dimensions
as the Series 75. Special face-to-face dimensions
are available.
The
standard body material is fabricated carbon steel.
Sleeve materials include Pure Gum Rubber, Neoprene,
Buna-N, Butyl, Hypalon, EPDM, and Viton.
Operation
of the Series 70 is the same as the Series 75,
utilizing double pinch bars to compress the flexible
rubber sleeve from above and below, closing simultaneously
on centerline when the handwheel is turned.
